IMPROVEMENT IN FEED-REGULATORS FOR CAR'BURETER'S.

Specification forming part of Letters Patent No. 212,502, dated February18, 1879 application filed June 22, 1878.

To all whom it may concern:

Be it known that I, WILLIAM H. REED, of Chicago, in the county of Cookand State of Illinois, have invented a new and valuable Improvement in Naphtha-Feed Regulators for Carbureters; and I do hereby declare that thefollowin g is a full, clear, and exact description of the same,reference being had to the annexed drawings, and to the letters andfigures of reference marked thereon.

Figure 1 of the drawings is a representation of a horizontal section ofmy automatic feedregulator. Fig. 2 is a bottom view thereof, and Fig. 3is a vertical central section of the same.

This invention relates to improvements in automatic feeders forgas-carbureters.

The object of the invention is to devise mean s for utilizing thegas-pressure to open the hydrocarbon-supply valves and deliver theenriching material to the carbureter.

The nature of the invention consists in the combination, with apipe-coupling joint having independent oil and gas inducts, of aweighted leverin said coupling, carrying at one side of its axis ofvibration valves closing the said inducts, and provided in the seat ofthe gasinduct valve with a trap-pipe, which delivers the hydrocarbon tothe carbureter, but excludes the gas from the fitting or coupling,whereby the gas-pressure is made to open the valves and admit gas andoil to the said coupling autoinatlilcally, as will be hereinafter morefully set 'ort In the accompanying drawings, the letterA indicates apreferably T-shaped coupling or joint, having the ends of its horizontalbranch closed by the screw plugs or caps a. The vertical branch n of thejoint is connected at its lower end to the vaporizing-chamber of acarbureter, and at its upper end to the mains or supply-pipes of abuilding.

B indicates a transverse rock-shaft, arran ged in the horizontal arm ofthe joint, and having its bearings in the adjustable screws 1). Uponthis shaft is a vertically-vibrating lever, D, from one end of which issuspended a conical valve, 0, and carrying upon the other an adjustableweight, a, the object of which will be hereinafter set forth. A

This valve is preferably of metal and made hollow, so as to besufiiciently light, and it fits snugly in a metallic seat-ring, d, inthe lower part of the vertical branch of the joint A, form ing a closejoint therewith.

From the apex of valve 0 projects downward a guide-rod, d, that passesthrough a guide, a, on a pipe, E. This pipe extends through theseat-ring d, is carried downward below the valve, is bent into V form,and then carried downward again a suitable distance, forming a trap, F,that prevents the upward escape of gas otherwise than through theseatring aforesaid.

Intermediate the seat-ring and the rockshaft B in the lower wall of thejoint is a tube, 1), the upper end of which is closed by a small conicalvalve, G, suspended from the lever D. The lower end of pipe I)communicates with a hydrocarbon tank arranged above the pipefitting A,and the gasoline or other hydrocarbon oil used is admitted into thefitting only through it. The valves G O are nearly balanced by theweight 0 on the lever, and the said weight is adjustable thereon, forthe purpose of securing the exact preponderance of the said valves.

The operation of this device is as follows: As gas is enriched in thecarbureter it passes up around the large conical valve, and accumu latesuntil it is sufiicient to float the said valve off of its seat. The gasthen escapes, in the direction indicated by the arrows, through thevalve-seat, and passes into the supplypipes ready for consumption. Theraising of the large valve thus described also lifts the valve G oil itsseat in the pipe b, and permits the hydrocarbon oil to pass into thefitting through said pipe. Equilibrium being reestablished above andbelow valve 0, it drops upon its seat, cuts oil the upward flow of gas,and, by lowering the small valve upon its seat, closes the induct-pipe,and thus cuts 0E the oil-supply from the coupling A. The oil in thelatter fills up the seal-tube E, and drips from its lower end into thecarbureter. The bend of tube E is at all times filled with oil, so thatthe pas sage of gas upward from the carbureter to the supply-pipesotherwise than by raising the valve is effectually prevented.

It will be seen from the above description that as gas accumulates underthe valve 0,

caused by the vaporizing of the hydrocarbon oil and the decrease of thelatter in the carbureter, the pressure of the gas raises the said valveand opens the oil-induct b automatically, thus supplying the hydrocarbonoil as fast as it is wanted.

The valves G O are adjustable upon their stems in order to their moreready adjustment on their seats, and the weight 0 is adjustable to orfrom the shaft B, in order to regulate the gas-pressure required toraise valves G and G.

What I claim as new, and desire to secure by Letters Patent, isv 1. In adevice for feeding hydrocarbon oils to carburetors, the combination,with the pipecoupling joint A, having a gas-passage way, a, the annularseat d, and oil-induct pipe b, of a transverse rock-shaft, B, lever D,vibrating on saidshaft, the adjustable weight 0, and the valves Gr and0, closing respectively the oil and gas indncts, substantially as setforth.

2. In an automatic oil-feeder for carburetin g machines, thecombination, with a .coupling having oil-induct b and gas-induct m,provided with an annular valve-seat, d, of the vibrating lever D,carrying valves G G, closing respectively the oil and gas inducts, andsuspended from said beam, an adjustable weight, 0, and a trap-pipe, E,substantially as set forth.
